Abstract

We construct a 4-invariant that extends the specialization of the

sl (2)

-weight system at

c = \frac{3}{8}

and satisfies a simple deletion–contraction relation.

期刊介绍： The European Journal of Combinatorics is a high standard, international, bimonthly journal of pure mathematics, specializing in theories arising from combinatorial problems. The journal is primarily open to papers dealing with mathematical structures within combinatorics and/or establishing direct links between combinatorics and other branches of mathematics and the theories of computing. The journal includes full-length research papers on important topics.
